Barbell Ab Rollout

Exercise Data
Main Muscle Worked: Abdominals
Other Muscles Worked: Lower Back, Shoulders
Equipment: Barbell
Mechanics Type: Compound

Tips: The elbows are to be locked and kept in a vertical line with the shoulders. Many ab wheel commercials show the user with their arms extended out but it is felt by some that this puts unnecessary stress on the shoulders and lower back. Keep the body locked in a straight position with no back "sag" when in the bottom position. All movement in this exercise is initiated by the hips, not the arms/lats. The emphasis should be on raising the butt as high as possible in a "piking" motion when in the upright part of the movement.
